Making an anti-war narrative is difficult, in no small part because the "anti-war" and the "narrative" can get in the way of each other.
Narratives, and especially popular narratives, have beginnings, middles, and ends; they have protagonists and antagonists; they have morals. They create out of war a recognizable story, which tends to rationalize, domesticate, and often justify the subject. Calum Marsh recently wrote at The Atlantic about the war boosterism of Lone Survivor, but even more thoughtful war narratives can run into difficulties. Full Metal Jacket, for example, shows war as violent and brutal and awful—but it also turns war into a coming-of-age narrative, where the horrors are part of Joker's transition from weak civilian to knowing warrior who is no longer afraid.
Even the determinedly anti-war novel All Quiet on the Western Front is not exempt. Remarques's heroic victims are still the heroes of the narrative; war is gothic horror, but that horror purifies and ennobles the guys on the ground, separating them from the power-hungry jerks back home who don't understand what war is really about. And if war is purifying and ennobling, if being good is equated with being at war, it's hard to see how that ends up being anti-war. It's not that Remarques and Kubrick see some good in the horror of war; rather, their narratives both end up treating the horror of war as the font from which good flows.
Maybe if you want an anti-war story, then, it might help to find a way to get rid of the story. The book Above the Dreamless Dead seems like a good place to test that theory. The volume, released to commemorate the 100th anniversary of the start of the Great War, is a collection of comics adaptations of World War I poems. The volume is not entirely anti-war—the poems come from a range of positions—but it does include many writers who condemned the fighting, from Siegfried Sassoon to Thomas Hardy.
Poetry is, of course, often less narrative-driven than novels or films, and the comics adaptations here serve to further fragment the text, interpolating spaces and images that break the rhetorical push of the poems apart rather than speeding them forward. If narrative tropes give war an air of inevitability and purpose, then a combination of comics and poetry seems like it should offer an alternative vision.
And in some cases it does. Frances Edward Ledwidge's poem "War," for example, presents war as ominous, incomprehensible, and cool in a Dr. Doom-rant kind of way. "I am love and hate and the terrible mind/of vicious gods, but more am I./ I am the pride in the lover's eye/I am the epic of the sea." Sammy Harkham's adaptation, though, undercuts the grandiosity and the power; rather than try to illustrate Ledwidge's Sturm und Drang, he shows a cute dog toddling through a lovingly detailed landscape, until it comes upon a bombed out building and a corpse. The twee deflation verges on satire; war can rant on and on about its grandiosity, but all it amounts to is carrion for a mildly puzzled, vaguely Snoopy-looking canine.
There are other effectively anti-war efforts as well. Hunt Emerson's earthy adaptations of the song "I Don't Want to Go To War" ("I'd rather stay in England … and fornicate me bleedin' life away!") makes civilian life seem as vivid as life at the front—a trick at which war films and novels often fail. Simon Gane's adaptation of Osbert Sitwell's "The Next War" uses illustrations of war memorials to great effect. The stillness of the monuments gives little space for action or excitement. The drama is in Sitwell's bitter recognition of lack of drama; the children called on to follow the same story as their parents—a story, Gane suggests, that inevitably turns those children to stone.
In other instances though, the poetry comics seem to have the same trouble opposing war as narratives do. Or, if not exactly the same trouble, then trouble nonetheless. For example, virtually nowhere in the book do we see a soldier killing anyone. These non-narratives can imagine the dead—frozen in place or detached from themselves. But they have trouble imagining acts of violence actually committed by someone against someone else, which seems like a failure to grapple with an important aspect of war.
Dispensing with narrative also can lead to a kind of aestheticization, where violence turns into appealing, static art. This is certainly the case in Rupert Brooke's basically pro-war "Peace," which intones, "Now God be thanked who has matched us with His hour," while Simon Gane draws a soldier dressing and walking off into the sunset.
